CAF Resistant Requirements:
- Product must pass 1000 hr CAF testing (100V, 85%RH, 85C).
- B Stage (pre-preg) is restricted to the following glass styles: 106/1067, 1080/1086, 2113/3313 and 2116.
- C Stage (cores) must have a resin content > 45%.
- Isola 370HR material is recommended for cost sensitive applications.
Notes: 7628 and 1652 glass should be avoided if CAF is a concern.
